Application filed April 13, 1909. Serial No. 489,607.

lb all whom it may concern:

Be it known that I, GILroIn) E. KnuMnL, a citizen of the United States,residing at Butland, in the county of Marshall and State of Indiana,have invented certain new and useful Improvements in Attachments forVehide-W heels; and I do hereby declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

My invention relates to new and useful improvements in vehicle wheelattachments and my object is to provide an extra tire and supporting rimtherefor and a further ob ect is to provide means for attaching theextra tire and rim to any one of the wheels of the vehicle and a stillfurther object is to provide means for securely locking the holdingdevices in position.

Other objects and advantages will be hereinafter referred to and moreparticularly pointed out in the claim.

In the accompanying drawings forming I part of this application, Figure1 is an elevation of a wheel rim and means for attaching the same to therim of the wheel on the vehicle, and, Fig. 2 is a transverse sectionalview through the rim of the vehicle and the extra rim, the section beingon an enlarged scale and through one of the fastening devices.

The main object of my invention is to overcome the objectionable featureof having to change the tire when traveling should the tire becomepunctured, and to this end, the usual form of tire (not shown), is attached to a rim 1, which may be of any preferred make and arranged to beattached to the rim 2 of the vehicle wheel and in order to quicklyattach the extra rim and tire without removing the punctured tire, Iprovide on the rim 1, clamping arms 3 and 4, said arms being preferably.arranged at the four quarters of the rim, the arms 3 being fixed to therim, while the arms 4 are adjustably attached thereto.

One end of the arms 3 is extended beyond and conformed to the contour ofthe outer edge of the rim and terminates in a hook 5, which hook isadapted to extend over and engage the flange 6 of the rim 2, therebysecurcly locking the rim 1 to the rim 2.

The arms 4 are mounted upon bolts 7 which extend downwardly through therim and through slots 8 in the arms 4, thereby giving the arms 4 aslight longitudinal movement, so that the hooks 5 may be read ilyextended over and into engagement with the flange 6, the arms 4 beingsecurely clamped in engagement with the rim 1, after they have beenengaged with the rim :2, by means of a cam 9, said cam being bifurcatedto receive the bolt 7 and is pivotally attached to the lower end of thebolt by extending a rivet or the like 10 laterally through the bolt andthe sections of the cam.

The cam is controlled by means of a lever 11 and the cam is so arrangedthat when the lever is in the position shown in full lines in Fig. 1,the arms 4 will be securely clamped against the rim 1, but when turnedto the position shown by dotted lines in said figure, the arms will befree and in position to be readily removed from engagement with the rim2.

When the lever 11 is swung to clamp the arms 4 in position, the face ofthe cam engages a clamping plate 12, which is provided with an opening18 to receive the bolt 7 and the arms 4 are held against swinging movement by providing guide loops 14 adjacent the outer edge of the rim 1,through which the arms 4 are introduced. The cam 9 is also so arrangedas to increase the pressure of the clamping plate and arm as the leveris swung to the position shown in full lines in Fig. 1 and in suchposition the pressure of the cam on the clamping plate and arm will holdthe lever firmly.

In addition to employing the arms for attaching the extra rim to the rimof the wheel, any suitable form of strap 15 may be attached to the extrarim 1 and in position to be extended around one or more spokes of thewheel to which the extra rim is attached.

In applying the extra rims, the levers are first turned to the positionshown by dotted lines in Fig. 1, when the hooks 5 of the arms 3 areengaged with the flanges of the rim 2 and the rim 1 then brought intoalinement with the rim 2 and the hooks of the arms 4 engaged with therim when the levers 11 are to be swung to the position shown in fulllines in Fig. 1 and all of said arms securely locked in engagement withthe rim 2. The strap 15 may be then attached to the spokes of the wheelto more securely retain the extra rim in position and should, for anyreason, one of the levers become loosened, said strap will retain theextra rim in position until such time as the vehicle can be stopped andthe loosened lever again adjusted. In this manner it will be readilyseen that the extra rim and tire may be very quickly applied to use andobviate the usual laborious task of removing the old tire andintroducing the new one in its place and it Will further be seen that asthe extra rim is securely locked in position, .the travel of the vehiclewill be the same as when the regular tire on the Wheel is in propercondition and being used.

That I claim is:

In an attachment for vehicle Wheels, the combination With a rim of theWheel, of a similarly constructed rim, arms applied to said firstreferred to rim and having laterally extending recurved portions adaptedto receive laterally the second referred to rim,

said arms having slots therein extending in the direction of thelongitudinal plane thereof, said first referred to rim also having guideloops receiving said arms, a bifurcated cam, a bolt having its stempassing through said cam, means for efi ecting connection between saidbolt and said cam, said cam having a lever-member for its manualactuation, and a clamping plate through which said bolt passes, engagedby said cam and itself engaging said arm.

In testimony whereof I have signed my name to this specification in thepresence of two subscrlblng Witnesses.
